Propanol, C3H7OH\text{C}_3\text{H}_7\text{OH}C3H7OH, can be dehydrated to produce propene, C3H6\text{C}_3\text{H}_6C3H6, as shown in the equation below:
C3H7OH→C3H6+H2O \text{C}_3\text{H}_7\text{OH} \rightarrow \text{C}_3\text{H}_6 + \text{H}_2\text{O} C3H7OH→C3H6+H2OCalculate the atom economy for the production of propene from propanol. (The relative formula mass, MrM_rMr, of C3H7OH\text{C}_3\text{H}_7\text{OH}C3H7OH is 60.0 and of C3H6\text{C}_3\text{H}_6C3H6 is 42.0.)
